Specific embodiment
In the following description, similar drawing reference numeral be used to describe in several views of attached drawing identical, similar or
Corresponding part.
The state that embodiment described herein relates generally to be maintained between user equipment and radio circuit is same
Step.
Referring to Fig. 1, the simplified block diagram of the wireless communication system 100 according to specific embodiment is shown.Wireless communication system 100
It may include fixed network 130, fixed network 130 includes many network stations for being connected to one or more central controllers.Fig. 1
One of network station, network station 105 are shown.Wireless communication system 100 may include many user equipmenies, such as portable phone, just
Plate, portable and mobile computer and portable and mobile apparatus etc. are taken, they are equipped with the nothing compatible with communication system 100
Line modem.Two such user equipmenies 110,120 are shown in FIG. 1.Wireless communication system 100 can be any nothing
Line communication system, wherein user equipment 110 operates at least two states: idle state and connection status, although the shape
State can have different titles in some communication systems.In many systems, all user equipmenies have both states.This
Only some examples of the system of sample are commonly referred to as CDMA IS-95, GSM, CDMA2000 EV-DO, UMTS, 3GPP UMB and 3GPP
LTE.Wireless communication system 100 can also be referred to herein as network 100.
Referring to fig. 2, state diagram 200 shows according to the user equipment 110 of specific embodiment and operates in the communication system 100
Other users equipment possible state in it is some.Show four states: off state 205, powering state 210, free time
State 215 and connection status 220.In off state 205, user equipment 110 consumes minimum amount of power --- and it is generally only sufficient
To detect the user for being powered on user equipment 110 instruction.From this off state, user equipment 110 is moved to powering state,
In this state, the processor of user equipment 110 is activated, and execute specific self-checking function (for example, memory check and
Battery inspection).Other function being not carried out in idle state 215 and connection status 220 can also be executed in powering state 210
Energy.For example, if user executes power-off command or if it is determined that the charged state of the battery of user equipment 110 is too low,
User equipment 110 can return to off state 205 from powering state 210.However, in normal circumstances, user equipment 110
It will enter in idle state 215.As described above, user equipment 110 is led to network station 105 nearby in idle state
Letter to confirm user equipment activity now with fixed network 130 and in idle state 215, and executes other systems guarantor
Function is held, is such as kept when user equipment moves in the geographic area of wireless communication system 100 and neighbouring network station
Communication keeps system clock and monitoring paging and control message from fixed network 130, and some of which can make user
Equipment 110 enters connection status 220.
May require from idle state 215 to the conversion of connection status 220 fixed network 130 and user equipment 110 it
Between successfully exchange several message.These will be specified in the system specifications for being used for specific wireless communication system 100 disappear
Breath.Connection status 220 is used to generate with such as voice, music, dynamic image distribution, audio streaming, interaction web browser, user
The form of order etc. transmits the appreciable information of usual user, and this can be commonly known as data communication.Often response
Enter connection status 220 in the behavior of the user of user equipment 110, the behavior all activation call start buttons in this way,
The order etc. of button, completion for being connected to website is answered in call.But can not have to the conversion of connection status 220
Occur in the case where the order of user from user equipment 110.For example, network can be mobile whole to initiate with calling user device
The audio call at end.User equipment 110 can convert back idle state 115, and can be used as the user of user equipment 110
The result of specific behavior carries out, such as order of starting calling hang up button or completion for disconnecting from website.It can to use
Another behavior that family equipment 110 converts back idle state 115 is that another party that voice connects terminates calling.
In some embodiments, when user equipment 110 detects that user equipment 110 has been lost the nothing of network 100
When line is electrically connected, user equipment 110 converts back idle state 215, and re-establishes connection.In addition, for example, by using by oneself
The order of the user of family equipment 110 can enter off state 205 from idle state or connection status.It is in user equipment
When in connection status 220, it usually executes at least some of the function that can also be executed in idle state.Can with even
It connects in state 220 and obviously simultaneously executes these functions in the other function of execution.For example, during audio call, by making
With time and/or channeling technology, user equipment can monitor the message in paging and/or control channel, without right
In any interruption of the audio of the audio call carried on a data channel.When user is when executing data communication, paging and control
The monitoring of message processed is usually only not aware of ground or that such data communication is not slack-off.
Although there is the system for attempting to avoid them to design, following situations may occur: wherein.At user equipment 110
In connection status 220, but user equipment 110 is recorded as being in idle condition in 215 by fixed network 130, that is, Yong Hushe
Standby 110 internal states are asynchronous with the state of user equipment 110 recorded by network 100, or more briefly, user equipment
110 is asynchronous with network 100.The situation causes excessive electric power in the user equipment 110 to consume, and can produce it is unfavorable
User experience because therefore user equipment and network cannot communicate with each other, until correcting the mismatch.The situation can be with
It generates in many systems, and may be not always able to find out cause.A kind of specific known example of the situation is in evolution
Occur in the Current implementations of UMTS Terrestrial Radio Access Network (E-UTRAN), evolution UMTS Terrestrial Radio Access Network (E-
It UTRAN) is the radio net used in 3GPP (third generation partner program) LTE (long term evolution) system.In the reality
In existing, it is found that it is generated in the exchange of following message: sending Connection Release from network station (NS) to user equipment (UE) and disappear
Breath.UE is sent back to because denying (NACK) message caused by error.Meanwhile NS sends safe mode command, the safe mode command
It is required that UE is encrypted and decrypted subsequent message, and connection release message is sent again.UE enters in safe mode, confirmation peace
Syntype order, but because the connection release message that it is not encrypted without acting on repeating transmission.UE is maintained at connection status 220
In, but during UE is recorded as being in idle condition by fixed network 130.
Another example with the nonsynchronous UE state of network 100 is when radio link becomes in network station 105 and uses
When unavailable between family equipment 110.In this case, UE 110 soon can be recorded as being in idle condition by network 100
In 215, but UE 110 can be for a long time in connection status 220.The long duration of nonsynchronous state can be sent out
It is raw, without the use of some of the unique technology described herein below.For example, when UE 110 is in LTE system and in DRX mould
When connecting in formula, which can be long lasting for one the reason is that UE less frequently is monitored when it is in DRX mode
Radio link.In some embodiments, such as timer approach, the method other than those of following can make UE
Back to idle state.These are only some examples that the what state can occur in LTE system.Because of similar original
Cause, the situation can occur in other kinds of communication system.
Referring now to Fig. 3, flow chart 300 show it is according to specific embodiment, for the user in wireless communication system 100
The flow chart 300 of some steps for the method that mode of operation in equipment 110 synchronizes.At step 305, in user equipment even
When connecing in state 220, message is received from network station.As described above, connection status 220 allows user equipment to be engaged in circuit switching language
Sound calling or packet switching network browsing, or other packet switched data communication behaviors are engaged in, such as use is assigned
Radio resource (radio-frequency spectrum and time distribution) for such purpose uploads or downloading content, such as video or sound
It is happy.In 3GPP LTE system specification, radio resource is identified as data radio carrying (DRB) or multimedia broadcasting and multicast
Service radio carries (MRB).DRB resource is used for the data communication between a user equipment and fixed network 130, and
MRB allows the broadcast from fixed network 130 to the data communication of one group of user equipment.Radio resource for data communication is not
Use when being assigned to user equipment in idle state 215.At step 310, user equipment determination is received in step 305
Message includes the address of user equipment, and the message is that in fixed network there is user equipment to be registered as in connection status
The message that should not be generated when in 220.User device responsive converts itself to idle shape in the determination at step 315
State.The state re-synchronization that user equipment is recorded the state of user equipment and fixed network 130 by the behavior.
Referring to fig. 4, flow chart 400 show it is according to specific embodiment, for the operation shape in wireless communication system 100
The step 405 of the synchronous method of state.User equipment in the connected state when monitor at least one signaling channel.It can be in some systems
Signaling channel is defined as paging or control channel in system.To signaling channel distribute with for data communication distribute those of it is different
Radio resource.The message that should not be generated when user equipment is recorded as in connection status by network is believed in signaling
One of received paging and control message on road.In 3GPP LTE system specification, it is wireless that radio resource is identified as signaling
Electricity carrying (SRB).SRB can be with bearing public control channel (CCCH), and the message that should not be generated is common control channel
Message.User equipment can access SRB when simultaneous transmission data using DRB or MRB by time and/or channeling.
Referring to Fig. 5, flow chart 500 show it is according to specific embodiment, for the operation shape in wireless communication system 100
Two steps of the synchronous method of state.One embodiment (Fig. 3) of step 505 expression step 310, wherein the determination of step 310
Further comprise: identifying that message is designated to change the state of user equipment from idle state to connection status at step 505
Become.When this is the case, user equipment at step 510 automatically to wireless communication system send connection establishes message, with
Step 315 (Fig. 3), which is in come into after idle state, re-establishes connection status.
User equipment can also execute other behaviors specified by the message.It is set for example, the message can be restriction user
Message that standby system parameter changes, specific addressing to user device address.User equipment is attempting to re-establish the connection
Those parameter changes are realized before.In the example of 3GPP LTE system, when message is to be addressed to the paging of user equipment to disappear
When breath, paging message has caused referred to as service requester, and the service request is normally by the state of user equipment from idle state
215 change into connection status 220.It can make in global system for mobile communications (GSM) and universal mobile telephone system (UMTS)
With the identical technology described relative to step 305-315 and 505-510, the GSM and UMTS are suitably adapted to believe signaling
Channel monitoring normally makes user equipment change into the message of connection status 220 from idle state 215.It is set according to specific embodiment
In the gsm system of meter, monitoring is in the letter for being identified as CCCH or PCCCH when user equipment can be designed in the connected state
Paging subchannel on road.If detecting paging message, 510 are thened follow the steps.In the UMTS designed according to specific embodiment
In system, monitoring is identified as the channel of PCCH when user equipment can be designed in the connected state.It is sought if detected
Class1 message is exhaled, thens follow the steps 510.
Referring to Fig. 6, flow chart 600 show it is according to specific embodiment, for the operation shape in wireless communication system 100
The step of method that state synchronizes.One embodiment (Fig. 3) of step 605 expression step 310, wherein the determination of step 310 is into one
Step includes: to identify that message is the control for being specified for using during connection is established or connection re-establishes at step 605
Message.In this case, the step 315 that equipment is transformed into idle state is executed, and this method is not to network station (NS)
Terminate in the case where sending response, even if can specify response.User equipment executes the function of normally specifying in idle state,
In the example of 3GPP LTE system, which is RRC connection reject message, message is established in RRC connection, RRC connection is built again
Vertical message is connected with RRC re-establishes one of refuse information.
In a particular embodiment, the message with reference to the step 305 of Fig. 3 and 310 descriptions is not to be designated to require to use by oneself
User equipment (still, as described in the step 310, is recorded as by any message of the response message of family equipment in fixed network
It should not be generated when in connection status 220).In this case, the step of user equipment is converted into idle state is executed
315, also, this method terminates in the case where not sending and responding to network station (NS).User equipment executes in idle state
